I damaged the dust cover on the brake cylinder while doing maintenance on the pads.

Question: Does this rubber dust cover come as a kit with other removable parts of the cylinder and is it easy to replace?

Any suggestion will help,

Thanks

Since I didn't yet received an answer I suspect I needed to be more specific. My car is the Elantra GT 2003 model with disk brakes on all 4 wheels. Certainly there must exist a kit containing rubber dust cover and other parts for refurbishing the brake cylinder unit as it would be too costly to change. Again, does anyone have experience with repairing brake cylinder on that specific model?

Thanks,
Gerard
